"Parallel" queries are queries that are executed in parallel, or at the same time so as to maximize fetching concurrency.
When the number of parallel queries does not change, there is no extra effort to use parallel queries. Just use any number of React Query's
useInfiniteQuery hooks side-by-side!
When using React Query in suspense mode, this pattern of parallelism does not work, since the first query would throw a promise internally and would suspend the component before the other queries run. To get around this, you'll either need to use the
useQuerieshook (which is suggested) or orchestrate your own parallelism with separate components for each
useQueryinstance (which is lame).
If the number of queries you need to execute is changing from render to render, you cannot use manual querying since that would violate the rules of hooks. Instead, React Query provides a
useQueries hook, which you can use to dynamically execute as many queries in parallel as you'd like.
useQueries accepts an array of query options objects and returns an array of query results:
